 * This annotation is only meaningful on a {@link DataBinder} field or constructor/method parameter.

 * It indicates that the annotated {@link DataBinder} is used to automatically bind all
 * corresponding widgets to properties of a data model (the model instance associated with the data
 * binder instance). The widgets are inferred from all enclosing fields and methods annotated with
 * {@link Bound} of the class that defines the {@link DataBinder} and all its super classes.
 * <p>
 * There can only be one auto bound {@link DataBinder} per class.
